ABB SD833 Module DCS
ABB SD833 is a robust digital input/output module designed for harsh industrial environments. Key specs include 32 digital inputs and 32 digital outputs, operating voltage of 24V DC, and a temperature range of -25°C to +70°C. It's typically used in process automation, particularly in oil and gas, and power generation sectors. Compared to the ABB CI855, the SD833 offers more I/O points but lacks the CI855's advanced diagnostic features. For applications requiring higher resilience, the SD833 is preferable over the ABB NBIO-31 due to its wider temperature range.
